buck50: Test and measurement firmware for "Blue Pill" STM32F103
===============================================================

**buck50** is open-source firmware that turns a "Blue Pill" STM32F103 development board (widely available for approx. US$1.50) into a multi-purpose test and measurement instrument, including:

**WARNING!** Incorrect hookups to the "Blue Pill" (or any other microcontroller's) ports may cause permanent damage. Examples: Connecting a push-pull output port directly to a positive voltage source or ground sink, or to another push-pull output on the same or different MCU set to the opposite polarity. Readers of this document and users of the firmware it describes assume all responsibility for their actions.
